Pit and mulching planting techniques to improve tree growth in windy and arid region

摘要

The present invention relates to a planting method for increasing rooting and growth of a planted tree in a windy and arid region unfavorable in growth of the tree and, concretely, to a pit mulching planting method, comprising the steps of: forming a pit with 60-70 cm of upper width, 45-55 cm of depth and 50-60 of a slope gradient on soil in the windy and arid region and positioning a tree in the pit; inputting earth into the pit to raise a surface of the soil from a base of the tree by 25-35 cm and planting the tree; and mulching the pit with dry grass around the base of the tree by 5-15 cm of thickness. The pit mulching planting method according to the present invention can achieve an effect of protecting against wind from all sides regardless of wind directions, and generates shadow in all directions to control evaporation of moisture from a tree stem and the soil and to be moisturized via wind protection and shadow generation. In addition, the dry grass with which the pit is mulched around the base of the planted tree by 5-15 cm of thickness can collect underwater or rainwater and provide organic materials to the soil.
